[ckan-dev] check for plugins

Wed Feb 22 16:43:03 UTC 2017

I would like to have a template-helper that tells me whether a certain plugin is loaded. This here works, but I'd be glad for any hints to achieve this less convoluted and more elegantly and future-proof:

import ckan.plugins as p

def eaw_check_plugin(pluginname):
    ifaces = (eval('p.{}'.format(name)) for name in p.interfaces.__all__)
    implemented = [item.name
                   for iface in ifaces
                   for item in p.PluginImplementations(iface)]
    return pluginname in implemented

Thanks,
Harald
